Do I get everyone an individual gift?

I just started getting very serious with this guy in august. We both have children from previous marriages. Christmas is coming up and I fully plan on getting his daughter gifts. He lives with his family. Including his school-age niece and nephew. I plan on sending a family gift from the Swiss Colony. Should I get his brother's kids gifts like my daughter and his daughter? Or does the family gift cover everyone? As a single mother this is financially challenging but I don't want to be rude.
